Jennette McCurdy & Ariana Grande’s Fight: Still Going On?

The end of Sam & Cat sounds like it’s also the end of a working relationship.

“Jennette is upset the show is not returning but she wanted to be treated with the same respect that Ariana was being treated with and also wanted more money,” a source close to the Nickelodeon stars told us.

Nick announced in an official statement that the show would be coming to an end after one season, with the last episode airing on July 17. That being said, the girls have had their ups and downs. With Jennette’s super sexy pics leaked onto the web, and Ariana’s career blooming more than ever, jealousy began to surround the set.

“I do now that there’s probably a lot of jealousy there — they’re young girls,” a different source close to Ariana told us . “I do know there’s a little bit of jealousy because Jennette owned Nickelodeon and then Ariana came along.”

Ariana & Jennette: Don’t Expect ‘Thanksgiving’ Together

Both girls, who have been friends since the show started, are planning on going forward professionally so don’t expect them to bash each other publicly.

“They are not close and will definitely not be best friends from this, they are both moving on from it as if it was a relationship ending,” a source told us.”They will play nice but they will only really see each other at award shows mostly, which is very easy to avoid people at, so no Thanksgiving dinners for them in the future.”

What do you think, HollywoodLifers? Should the girls make up and be friends again? Or is the friendship doomed? Let us know.
